Potential Blitzcrank Rework? "New E/R ability"

E: Rocket Punch - Fires a punch (with left arm) that knocks back the first target hit. Same range as Q. Damage Increased the closer Blitzcrank is to enemy punched.

R: Discharge - Unleashes all the charge from power core in an AOE cone, dealing damage and disabling all enemies hit for a short duration. (Blitzcrank becomes temporarily disabled as well, and must recharge for a second after using this ability)

Blitzcrank feels like a weak pick for teams these days, as Pyke does everything and more that a blitzcrank can do, thresh has way more utility, and other champions are just better picks. Blitzcrank may be a robot, but 'it' still needs some love too.

A champion's entire win condition shouldn't be 1 ability (hook)

(Teetering with more ideas, Blitz W could have a knockup on 3rd or 4th basic attack [Mean Left Hook])
